Fail to import a LESS sheet inside a vue file

[aleksejevski]

Expected behavior

These code should work correctly:

<style lang="less">
  @import "../assets/block";
</style>

Actual behavior

Compiling the vue file failed with these words:

�   (vue plugin) '../assets/block.less' wasn't found. Tried - ../assets/block.less,..\assets\block.less
src\components\block.vue

The file "../assets/block.less" really exists. I have tried importing the file in the form below, but it still doesn't work:

<style lang="less">
  @import "..\assets\block";
</style>

Just such thing is returned:

�   (vue plugin) '..\assets\block.less' wasn't found. Tried - ..\assets\block.less,..\assets\block.less
src\components\block.vue

Steps to reproduce the behavior
